Sierra Pea: A Charming Native Wildflower for Western Gardens
If you’re looking for a delightful native wildflower that practically takes care of itself, let me introduce you to the Sierra pea (Lathyrus nevadensis nevadensis). This unassuming little beauty might not be the showiest plant in your garden, but it brings a quiet charm and important ecological benefits that make it a wonderful addition to naturalized landscapes.
What is Sierra Pea?
Sierra pea is a native perennial forb that belongs to the pea family. Unlike its woody cousins, this herbaceous plant stays soft and green, dying back to ground level each winter before emerging fresh in spring. You might also see it listed under its synonym, Lathyrus nevadensis S. Watson var. nevadensis, but don’t let the scientific names intimidate you – this is simply a humble wildflower with big heart.
Where Does Sierra Pea Call Home?
This native gem is perfectly at home across the western United States, naturally occurring in California, Idaho, Oregon, and Washington. As a true native of the lower 48 states, Sierra pea has evolved alongside local wildlife and climate conditions, making it an excellent choice for gardeners who want to support their local ecosystem.
